Be itknown that I, ALFRED-J. SWING, a' citlzen; of the United States. residing at Cincinnati, in the county of Hamilton and State of Ohio, ha'ye invented certain new and useful Improvements 1n Perforating- Machines, of which the following is a specification.

- My invention relates to a machine for perfora-ting continuous strips of paper in series One of,the objectsof my invention is to l provide means. for controlling the operation 51 int a series of punch-members electrically 1 {through i the feed of a perforated master .sheet, 'whereby synchronous action can be ha d IIPQI'I a series of multiple strips 'of paper.

finotlier objectiof my invention is to provide' a series of make, and break electric circuit contact members, between which a perforated master strip is fed, with means for constantly reciprocating one of the make and break- In e nbers, and means for prede- "termiiia'bly,finitially breaking the circuit prior to ,the'; separation of the serial make and break'contact members. f r i Another object of my invention is to pro- ,Videa, constantly actuated plunger cross-H head, for operatinga seriescf punch-membeis, with iineans interposedqbetween said plunger and punches electrically controlled for independently operating each punchmembcrvof the serie'siv a Various features ofmy invention are m ore fullyi setgfortlr in' the description'of the accompahying jdrawings, forming a part of this sp'ec'ifit'ationgin which p I Figure 1're1n'eseiitsxa "top plan v ewof my -lnus'ie-sheet' perforation maclnne; illusthe punchcenti olling mechanism of the several' series 'ofthepunch members of one perforating set.

4, 5, represent; eccentric di'sks fixed to the shaft 3, carrying the pitman levers 6 pivotally connected to the cross-head plunger 7, slidably mounted. in ways formed between two of the supports 2. y l v As illustrated, the pitmenware preferably connected at eachend, of the cross-head plunger. v v

8 represents a plate secured to the cross head plunger and preferably insulated therefrom to avoid the short circuiting of the electriccircuit, said plate being provided with top and bottom flanges supporting a series. of vertically movable switch members, adapted to be reciprocated with the cross-head plunger. hers comprise a series of pins 9,-projected through the flangesof the plate 8, each having a collar 10, adapted to engage against the inner face of the lower flange of the plate 8, and acoiled spring 11 interposed between said collar 10 and upper flange, for maintaining the free ends'or ecntact' ends under tension downwardly. I'2""represents .an insulator plate horizontally supported beneath the cross-head plunger, provided witha series of contact members 13, in respective alinement with the c'ontactpins 9 carried by the cross-head plunger. I Thus,-

the contact pins 9 will engage with thei' respective contact members13, comple tiiigd;

It is obvious, however, thatv this intermittent. feed relative to the reciprocation of the contact members, may be variously modified,

- multiple continuous strips of paper for reproducing a given musical composition or record. The master strip is preferably pro- .vided with. the marginal notches 17, upon each edge "thereof, adapted to engage with coincidently shaped lugs orprojections I 19 formed'on theperiphery of the feed roller 20, fixed to a feed shaft 21, said shaft extending. horizontally across the machine to receive the feed roller of a series of strips. Said shaft is fed as follows represents an eccentric disk fixed to the shaft 3, and

23 a pitman lever-mounted on said disk 22, its free end provided with an oblong slot 24,'through which a pin 25 projects, said pin is fixed to the pawl lever 26, loosely j pivoted on the feed shaft 21. 27 represents a pawl pivoted to the pawl lever 26, adapted to engage with the teeth of the ratchet wheel 28, fixed to the feed shaft 21. Thus, upon each reciprocation of the pitman 23, the ratchet wheel 28 will be fed forward one tooth or more', as desired.

It -'is desirable to have the'electric circuit passing through the'contact members 9, 13, broken in advance of the break between said .members, in order to avoid sparking a such point and therebyprevent injury to the master sheet and oxidation of contact members, Which, if c'ontinued,would produce a scale of non-conducting substances, preventing va circuit being formed. This is accomplished 'as follows :'-29 represents a break wheel fixed to the mainshaft 2, provided with a contact plate 30, segmentally extended around the periphery of said break wheel 29, see Fig. 5; and 31, 32' represent contact fingers engaging against the periphery. ofsaid'break wheel ,29, said fingers.

being short-circuited when they engage over the con-tact plate 30, closing the partial circuit to the contact members 9, 13; this contact being so arranged relative to the rotation of the main shaft 3, controlling the reciprocation of a circuit controlling plunger,

soas to break the electric circuit to the conaway from the contact member 13. It is obvious, however, that various means may be employed for producing a non-arcing or sparking break, without departing from the features of my invention. Further. the reciprocation of the contactmembers and the 1 master sheet feed are intermittent relative to each other, that is, the master sheet is at invention.

supported u on,the frame 1, beneath the cross-head p unger 35, provided with an intermediate paper feeding slot 37, between which multiple strips of paper are fed and perforated, said slot extending horizontally the width of the paper.

38 represent movable punch-members projected into the punch orifices formed with stationary punch-member 36, with each member provided with a head-plate 39, projected forwardly and adapted to be engaged in one movement ofthe plunger.

41' represents a shoulder formed upon the plunger 35, adapted to engage with the inin the downward movement of the plunger, when the connecting bars are moved under to impart downward movement to the movable punch members 38. These connecting bars 42 are individuallycontrolled electrically by means of electro-magnets when the same are respectively thrown into circuit. through the connections of'themake and trolled by the plunger 7. A punch operating bar 42 is provided for each of the mov ablepunchsmembers of the series, the number required being equal to the range to accommodate for various notesin a musical composition or actions of a musical instrument. v j

As illustrated in the drawings, each punch bar 42 is actuated preferably by a solenoidmagnet and lever mechanism, in which an indlvidual magnet'operates the given punch member of all the sets of the series. and in which the electriccircuit to each magnet is control-led individually by a'given make and l break contact member. heretofore described, a mounted upon the plunger 7.

, All of the magnets and actuated mechanism thereof are similarly constructed and connected to a lever 43. fixed upon a rock shaft 44, suitably 'journaled in bearings 1-3.

is desirable to separate the punch bars 42 9f the series from each. other, to prevent contact or engagement betweenrthe same, and

;thisvlis accomplished by means of a'spacing 40 bar or plate 54,,{provided with. notches through, which-the punch bars 42 project.

,This feed maybe variously modified and doesnot form a special :fleatureof this invention.

As illustrated, the feed'rollers 57 of the series are of smaller diameter than the master sheet feed roller 20, to provide a differential ratio of 'speed between thev two, enabling the production tofan elongated perforation, denoting the value o fa note, instead of producing or reproducing the serial perforations for a given value ofa note, as that of the master sheet. .Such elongated perforations when the record sheet is in use produces a prolonged action according to the value of .the note, which could not be obtamed in the serial perforations for the value of a given note formed inthe masteri--- sheet, but are more desirable in the master sheet in a proper reproduction of a recordjfl Having described my invention, I claim 1.
